[0111] Based on the initialization of the fully mechanized mining face, specify the mobilization range; wherein, the specified mobilization range is to interactively specify the mining footage of the return air lane and the transport lane of the fully mechanized mining face, or interactively delineate the mobilization range; supplement the mobilization parameters, calculate the coal mobilization amount of the fully mechanized mining face, and generate the mobilization area of ​​the fully mechanized mining face; wherein, the mobilization parameters at least include: actual mining thickness, coal falling thickness, thickness loss, coal falling loss, roadway top and bottom loss and stage coal pillar loss; store the mobilization attribute data of the fully mechanized mining face in the mobilization area of ​​the fully mechanized mining face, and realize the binding of the fully mechanized mining face and the mobilization area of ​​the fully mechanized mining face based on the name of the fully mechanized mining face. The mobilization attribute data of the fully mechanized mining face at least include: the name of the fully mechanized mining face, loss amount, mining amount, mobilization amount, mining rate, mining area loss amount, mining area mining amount, mining area mobilization amount, mining area recovery rate, mine loss amount, mine mining amount, mine mobilization amount, and mine recovery rate. The mine amortization amount is calculated based on the mine's permanent coal pillar amortization coefficient and the mining area's mobilization amount, and the mine amortization amount, geological and hydrological losses and reported losses are bound to the boundary of the fully mechanized mining face.

[0112] In addition, the specific method of updating the unmined area and the goaf area is: based on the fully mechanized mining working face, specify the N-times mobilization range of the fully mechanized mining working face, and generate N mobilization areas of the fully mechanized mining working face; wherein, the value range of N is an integer from 1 to N; based on the N mobilization areas, update the goaf area of ​​the fully mechanized mining working face and the unmined area of ​​the fully mechanized mining working face until the fully mechanized mining working face is all goaf areas; wherein, the goaf area is the union of N mobilization areas, and the unmined area is the area of ​​the fully mechanized mining working face excluding the goaf area.

[0113] For example, in this embodiment, based on the fully mechanized mining face, when the fully mechanized mining face is calculated for the first time, the fully mechanized mining face mobilization range is specified to calculate and generate the first mobilization area of ​​the fully mechanized mining face, and the unmined area and the goaf area of ​​the fully mechanized mining face are updated;

[0114] Then, after the first mobilization calculation, based on the updated comprehensive mining working face, the second mobilization calculation is performed on the comprehensive mining working face, the second mobilization range is specified and the second mobilization area of ​​the comprehensive mining working face is generated after calculation, the first mobilization area and the second mobilization area of ​​the comprehensive mining working face are merged to update the goaf area of ​​the comprehensive mining working face, and the unmined area of ​​the comprehensive mining working face is also updated synchronously; by analogy, when the comprehensive mining working face is calculated for the Nth time, the Nth mobilization range is specified and the Nth mobilization area of ​​the comprehensive mining working face is generated after calculation, the first mobilization area to the Nth mobilization area of ​​the comprehensive mining working face are merged to update the goaf area of ​​the comprehensive mining working face, and the unmined area of ​​the comprehensive mining working face is updated synchronously until the comprehensive mining working face is mined and the comprehensive mining working face is entirely a goaf area.

[0115] Step S104: Determine resource reserve mining data by multi-dimensionally superimposing the utilization area of ​​the fully mechanized mining face in different time periods and the reserve block boundaries in the resource reserve calculation diagram, and dynamically update the resource reserve calculation diagram.

[0116] In this embodiment, the resource reserve mining data is determined by multi-dimensional superposition of the utilization area of ​​the comprehensive mining face in different time periods and the reserve block boundaries in the resource reserve calculation diagram, and the resource reserve calculation diagram is dynamically updated. Specifically, the utilization area of ​​the comprehensive mining face and the utilization data of the comprehensive mining face in different time periods are cumulatively calculated and superimposed with the reserve block boundaries in the resource reserve calculation diagram, and the mobilized resources, reserves, area and reserve increase and decrease changes of each reserve block are calculated according to the superposition ratio. Then, based on the mobilized resources, reserves, area and reserve increase and decrease changes of each reserve block, a reserve utilization legend is generated, and based on the reserve legend resources, reserve legend reserves, reserve legend area of ​​the resource reserve calculation diagram and the reserve utilization legend resources, reserve utilization legend reserves, and reserve utilization legend area, the reserve legend in the resource reserve calculation diagram after mobilization is determined, and the resource reserve calculation diagram is dynamically updated.

[0117] In this embodiment, the reserve legend in the resource reserve calculation diagram after mobilization is determined specifically by: subtracting the reserve legend resource volume, reserve legend reserve, and reserve legend area of ​​the resource reserve calculation diagram from the reserve legend resource volume, reserve legend reserve, and reserve legend area of ​​the resource reserve calculation diagram, respectively, to obtain the reserve legend in the resource reserve calculation diagram after mobilization, thereby completing the dynamic update of the resource reserve calculation diagram.

[0118] In addition, the different time periods in this embodiment can be ten days, months, quarters, half years, and years. The utilization data of the comprehensive mining face include the sum of the utilization of the comprehensive mining face in different time periods, the sum of the amortization of the coal pillars in the mining area, the sum of the amortization of the permanent coal pillars in the mine, the sum of the geological and hydrological losses, and the sum of the reported losses. The resource reserve mining data include the utilization or amortization or loss of the reserve block segment, the reserves, the area, and the change in the increase or decrease of the reserves. The boundary of the reserve block segment is the range delineated according to certain rules, and the reserve legend is a composite entity with information such as name, coal type, resource, resource level, reserves, reserve level, area, coal thickness, inclination, bulk density, etc. The reserve block segment and the reserve legend are in a one-to-one correspondence. The units of resources and reserves can be tons, thousands of tons, and ten thousand tons. The unit of area can be square meters, thousands of square meters, and ten thousand square meters.

[0119] In addition, the dynamic update of the resource reserve calculation map includes at least one of the following methods:

[0120] Method 1: Based on the utilization area of ​​the fully-mechanized mining face, the utilization data of the fully-mechanized mining face and the stage coal pillar loss, the mining area scope of the fully-mechanized mining face is drawn, and the increase and decrease of the reserve blocks and the reserve utilization amount within the mining area scope of the fully-mechanized mining face are obtained based on the overlay calculation of the mining area scope and the reserve block boundaries in the resource reserve calculation diagram, the reserve legend in the resource reserve calculation diagram is updated and the reserve utilization legend is drawn.

[0121] Method 2: Calculate the reserve block amortization amount based on the current mining area amortization region of the comprehensive mining working face, the mining area amortization amount of the comprehensive mining working face and the reserve block boundary in the resource reserve calculation diagram, update the reserve legend in the resource reserve calculation diagram, and reversely calculate the reserve amortization area based on the amortization amount, and draw the reserve utilization legend.

[0122] Method 3: Specify the reserve legend in the resource reserve calculation diagram, and directly amortize the mine amortization to the resource volume in the reserve legend in the resource reserve calculation diagram. When the resource volume in the specified reserve legend is insufficient, specify the next reserve legend until the mine amortization is completed, and draw the reserve utilization legend synchronously.

[0123] Method 4: Based on the geological and hydrological amortization of the comprehensive mining face, specify the geological and hydrological loss areas, and superimpose the calculations with the reserve block boundaries in the resource reserve calculation diagram, amortize the geological and hydrological losses to the resource volume in the reserve legend of the resource reserve calculation diagram, and draw a reserve utilization legend.

[0124] Method 5: Based on the reported loss volume of the fully mechanized mining face, specify the reported loss volume area and the reserve block boundary in the resource reserve calculation diagram for superposition calculation, amortize the reported loss volume to the resource volume in the reserve legend in the resource reserve calculation diagram and draw the reserve utilization legend.

[0125] In the above five methods, the increase or decrease variation is the difference between the actual production of the reserve block and the production of the reserve block. The actual production of the reserve block is the actual production calculated by multiplying the ratio of the area of ​​the reserve block within the mining area to the mining area by the superimposed calculation and the production of the mining area; the production of the reserve block is the mining area calculated by the ratio of the area of ​​the reserve block within the mining area to the mining area, and is calculated by the coal thickness and bulk density in the reserve legend in the resource reserve calculation diagram. The calculation formula is reserve block production = coal thickness in the reserve legend * bulk density in the reserve legend * mining area.

[0126] In addition, the reserve production legend can be the style of the reserve legend, and the specific generation method is: the position of the reserve production legend is based on the original reserve legend and moved around a certain distance, which can be the distance of a reserve legend radius. The resource volume of the reserve production legend is the reserve production volume, or the amortization volume, or the loss volume; the reserve volume of the reserve production legend is the calculated resource volume*(original reserve volume / original resource volume), especially, when the amortization volume or loss volume is calculated, the reserve volume is 0; the area of ​​the reserve production legend is the production area, amortization area, or loss area, the name of the reserve production legend is the name of the original reserve legend plus "production" or "loss" for identification, and the coal type, resource level, reserve level, coal thickness, inclination, etc. of the reserve production legend are the values ​​corresponding to the original reserves. The increase and decrease changes are written into the reserve production legend in the form of attributes. The amortization of permanent coal pillars in a mine includes the amortization of coal pillars at the boundary of the mine, the amortization of coal pillars in the industrial square of the mine, and the amortization of other permanent coal pillars in the mine. The amortization of the amortization or loss amount to the resource amount in the reserve legend of the resource reserve calculation diagram is the resource amount in the reserve legend minus the amortization or loss amount.

[0127] Step S105: storing resource reserve data of different dimensions into the coal mine resource reserve spatial database, and generating a variety of coal mine resource reserve reports based on different reserve report templates.

[0128] The resource reserve data of different dimensions are stored in the coal mine resource reserve spatial database; wherein the resource reserve data of different dimensions include: reserve graphic data and reserve attribute data of different time periods, and the reserve graphic data and attribute data of different time periods are distinguished by time stamps; the reserve graphic data at least include: resource reserve calculation diagram, reserve three-quantity diagram, reserve production diagram and reserve loss diagram; the reserve attribute data at least include: reserve legend data, reserve three-quantity data and reserve production data

[0129] The report template library stores templates of various styles, and the reserve report template can be set based on the report template library; then, based on the coal mine resource reserve space database and the reserve report template, target resource reserve data of different dimensions can be obtained;

[0130] Since the target resource reserve data of different dimensions include reserve graphic data and reserve attribute data of different time periods, the reserve graphic data and attribute data of different time periods are distinguished by time stamps.

[0131] Therefore, based on the reserve report template and the target resource reserve data, a coal mine resource reserve report is generated.

[0132] The reserve legend data includes at least the name, coal type, resource quantity, resource quantity level, reserves, reserve level, area, coal thickness, inclination, bulk density, and whether it is retained.

[0133] The three-quantity reserve data include at least: year and month, mine name, coal seam name, level name, mining area name, working face name, three-quantity category, geological reserves, recoverable reserves, coal seam inclination, coal seam thickness, bulk density, and plane area.

[0134] The reserve utilization data include at least: year, month, mine name, coal seam name, level name, mining area name, working face name, coal mining method, bulk density, utilization area, coal thickness, actual mining thickness, coal thickness, other losses of working face, loss of working face, utilization of working face, mining volume of working face, amortization coefficient of coal pillar in mining area, coal output of mining area tunnel, stage coal pillar loss, top and bottom loss of tunnel, other losses of mining area, loss of mining area, mining volume of mining area, utilization of mining area, amortization coefficient of coal pillar at mine boundary, amortization coefficient of coal pillar in mine industrial square, amortization of permanent coal pillar in mine, geological and hydrogeological loss, loss report, mine loss, mining volume and utilization of mine. The types of reserve report templates include at least three reserve tables, monthly working face utilization table, end-of-period reserve table, annual utilization table, annual increase and decrease table and dynamic table of mine resources. Repeat steps S103 and S104 to dynamically update the resource reserve calculation diagram to complete the update of the entire coal mine resource reserves, and when the new comprehensive mining working face division is completed, repeat steps S101 to S105 to update the entire coal mine resource reserves, and dynamically update and display the coal mine resource reserves graphical report.
